A 15-year-old high school soccer player hanged himself after he received insulting messages from bullies on a social media app, according to reports.

George Hessay, from Goole, East Yorkshire, UK, was using the Sayat.me website — which allows users to post anonymous “feedback” about their friends — when he received the offensive comments, The Telegraph reported.

The teen was found hanging on May 10.

The site, based in Estonia, was designed for business users seeking “constructive, honest feedback” from colleagues and clients — but many of its 30 million users are believed to be teenagers, according to the site.

Hessay was a student at the Snaith School, where he played for the Snaith Comets football team.

Hessay’s friend Joely Baxter posted a tribute to the teen on Facebook, calling him “such a nice boy who cared about everyone and made sure everyone was OK.”

“He really didn’t deserve what happened to him,” Baxter wrote. “Nobody does and I think that whoever wrote things about him on that stupid Sayat.me thing should be ashamed and grow some balls and own up to it because whoever did it was sick in the head.”

The Snaith Comets team told The Telegraph that Hessay was “a great team player.”

The boy’s death is not being treated as suspicious, a Humberside Police spokesman told The Telegraph.

Hanna Talving, the CEO of Sayat.me, told the Telegraph on Thursday that the site was taken offline following Hessay’s suicide.

“We have been made aware by police that they are investigating a bullying related suicide and we offer our sincere condolences to those affected by this loss,” she said in a statement. “We deplore bullying of any kind and want it to have no place on our site. We will offer any assistance we can to the police. We have suspended use of the website to show how seriously we take these matters.”
